[0024] Embodiment 1, referring to Figures 1-4 , a reactor for low - rank coal liquefaction treatment that facilitates solid - liquid separation, includes a reactor 1 and a heating furnace 2. The reactor 1 passes through the middle of the heating furnace 2.

A top cover 3 is provided at the top end of the reactor 1. A stirring mechanism is installed on the top cover 3. A gas detector is installed on the inner wall of the top cover 3. A discharge port 10 is provided at the bottom end of the heating furnace 2 where the reactor 1 is located. The bottom end of the heating furnace 2 is connected to a discharge assembly. Connecting rods 9 are fixedly installed on the outer walls on both sides of the heating furnace 2. A collection box 7 is installed between the bottoms of the two connecting rods 9. A separation assembly is installed on the collection box 7. A feeding pipe 5 is provided on the top cover 3, and a sealing cover is provided at the top end of the feeding pipe 5. An exhaust valve 14 is installed on the side wall of the reactor 1 at the top and above the heating furnace 2;
[0025] The separation assembly includes an insertion sleeve 17 fixedly installed at the bottom on one side of the collection box 7. An L - shaped insertion plate 16 is inserted into the insertion sleeve 17. A filter plate 6 is fixedly installed at the end of the horizontal section of the L - shaped insertion plate 16 in an inclined manner. Filter holes are equidistantly arranged on the filter plate 6. A filter net is fixedly installed at the top end of each filter hole. A vibration motor 15 is installed on the upper end surface of the horizontal section of the L - shaped insertion plate 16. The model of the vibration motor 15 is SXC - 60 - 4. The vibration generated by the rotation of the eccentric block on the vibration motor 15 drives the L - shaped insertion plate 16 and the filter plate 6 to vibrate together. The filter plate 6 is located above the collection box 7. A drain valve is installed at the bottom end on one side of the collection box 7;
[0026] The stirring mechanism includes a servo motor 4 fixedly mounted on the outer wall of the top end of the top cover 3. The output end of the servo motor 4 extends into the interior of the top cover 3 and is connected to a U-shaped frame 19. Stirring rods 20 are evenly fixed on the vertical sections on both sides of the U-shaped frame 19. During the reaction process, the servo motor 4 drives the U-shaped frame 19 and the stirring rods 20 to rotate, fully stirring the reactants to ensure the completeness of the reaction.
[0027] The discharging assembly includes electric push rods 12 symmetrically connected to both sides of the lower end face of the heating furnace 2. The bottom ends of the two electric push rods 12 are connected to a lifting rod 13. The middle of the upper end face of the lifting rod 13 is fixedly provided with a support rod 11. The top end of the support rod 11 extends from the discharging port 10 into the interior of the reaction kettle 1 and is connected to a sealing block 18. The diameter of the support rod 11 is smaller than the diameter of the discharging port 10.
[0028] Limit strip-shaped holes 8 are formed in both of the two connecting rods 9. The two ends of the lifting rod 13 are respectively slidably clamped with the two limit strip-shaped holes 8, ensuring the stability of the lifting rod 13 and preventing it from shaking easily, thereby ensuring the sealing effect of the sealing block 18 on the discharging port 10.
[0029] Working principle: After the reaction of the reactants in the reaction kettle is completed, a gas detector can detect the concentration and components of the gas in the reaction kettle, and the gas detector can transmit the detected information to an external display for display. Through the pipeline connected to the exhaust valve 14, opening the exhaust valve 14 can discharge the gas. By contracting the electric push rods 12, the lifting rod 13 is driven to rise, so that the lifting rod 13 drives the support rod 11 and the sealing block 18 to rise, and the reactants can be discharged from the discharging port 10. The reactants fall onto the filter plate 6. Through the filtering action of the filter holes and the filter net, the solid and liquid of the reactants are separated. The liquid falls into the collection box 7 through the filter holes, and the solid falls outside the collection box 7 along the filter plate 6. By opening the drain valve, the liquid can be discharged. During the filtering process, the vibration motor 15 is turned on, and the vibration of the vibration motor 15 can drive the filter plate 6 to vibrate together, enabling the solid to be quickly discharged and improving the filtering efficiency. In the above process, there is no need to transfer the reactants for filtration after the reaction is completed. The reactants are directly discharged from the reaction kettle to achieve solid-liquid separation, greatly saving time. During the separation process, people do not need to approach, which can prevent high temperature from causing harm to the human body, and it has good practicability.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
